A cheesesteak is a long, crusty roll filled with thinly sliced sautéed ribeye beef and melted cheese. Generally, the cheese of choice is Cheez Whiz, but American and provolone are common substitutions. The art of cheesesteak preparation lies in the balance of flavors, textures and what is often referred to as the drip factor. Other toppings may include fried onions, sautéed mushrooms, ketchup and hot or sweet peppers. A lot of resto nowadays offers a large variation of cheesesteaks suited to your taste.
